What's the problematic line (hippo.c:154) doing? What's before
that in the hippobuild function?
I wouldn't put much stock in the "Cannot access memory" message ... that
just means gdb is confused, which it frequently is. But possibly
building with -O0 would make it less confused.
BTW, I gather from the reference to OidFunctionCall3Coll that you're
using PG 9.5 or older. It'd be a good idea to switch to 9.6, which has
noticeably cleaner indexam APIs that allow some compiler error checking
on those calls.
